In this paper, the authors investigate the effect of positive income shocks on the mental health of adolescent girls using experimental evidence from a cash transfer program in Malawi. They find that the provision of monthly cash transfers had a strong beneficial impact on the mental health of...

Despite their explicit focus on reaching the poor, many community driven development (CDD) projects have been found to be only mildly pro-poor in their funding allocations. This paper presents evidence of an explanation that has been overlooked in the CDD literature to date: the requirement that...

Conditional Cash Transfer programs are "...the world's favorite new anti-poverty device," (The Economist, July 29 2010) yet little is known about the specific role of the conditions in driving their success. In this paper, we evaluate a unique cash transfer experiment targeted at adolescent...

Recent evidence suggests that conditional cash transfer programs for schooling are effective in raising school enrollment and attendance. However, there is also reason to believe that such programs can affect other outcomes, such as the sexual behavior of their young beneficiaries. Zomba Cash...

As of 2007, 29 developing countries had some type of conditional cash transfer program in place, with many others planning or piloting one. However, the evidence base needed by a government to decide how to design a new conditional cash transfer program is severely limited in a number of...

Long-acting reversible contraceptives are highly effective in preventing unintended pregnancies, but take-up remains low. This paper analyzes a randomized controlled trial of interventions addressing two barriers to long-acting reversible contraceptive adoption, credit, and informational...

This paper conducts a large, narrative literature review of interventions that seek to (1) increase educational attainment, (2) delay childbearing, and/or (3) delay marriage for adolescent girls in developing countries. Using 104 interventions from 70 studies, predominantly in developing...

Long-acting reversible contraceptives are highly effective in preventing unintended pregnancies, but take-up remains low. This paper analyzes a randomized controlled trial of interventions addressing two barriers to long-acting reversible contraceptive adoption, credit, and informational...

We evaluated Girl Empower - an intervention that aimed to equip adolescent girls with the skills to make healthy, strategic life choices and to stay safe from sexual abuse using a cluster-randomized controlled trial. Girl Empower led to sustained improvements in several important domains,...

We formalize the optimal design of experiments when there is interference between units, i.e. an individual's outcome depends on the outcomes of others in her group. We focus on randomized saturation designs, two-stage experiments that first randomize treatment saturation of a group, then...
